To all whom it may concern:

Be it known that I, WILLIAM A. U'r'rz, a citizen of the United States,residing at Fort Worth, in the county of Tarrant and State of Texas,have invented certain new and useful Improvements in Life-SavingAttachments for Locomotive-Cabs, of which the following is aspecification.

My invention relatesto safety devices for escaping from locomotiveengine cabs, and more particularly to a detachable carrier to bedischarged from the engineers cab in case of danger; and the object isto provide a carrier or protecting device into which the engineer caninclose himself instantly in time of danger and which device will beautomatically detached from the cab and delivered to the ground or otherplace for the protection of the engineer.

The object is to provide a device which will inclose the engineerandprotect him against falling on the ground or stones or other dangerousobjects and which can be sealed air and water tight and provided with avalve which the engineer can operate. The same device is equally asavailable for the fireman as for the engineer.

The object is to protect the engineer and the fireman against fire andhot water or steam and to provide a ready means of escape from theengine cab.

One object is to provide a carrier or deliverer which cannot be crushedor will not be crushed in times of accident and danger. The carrier canbe so arranged relative to thethrottle valve lever and the angle cock ofthe air-brake system and the sanding devices that all these devices willbe actuated by the falling of the carrier out of the cab. A The. enginemay also be equipped with reversing devices which can also be actuatedby the discharge of the carrier.

Other objects and advantages will be fully explained in the followingdescription and the invention will be more particularly pointed out inthe'claims.

Reference is had to the accompanying drawings which form a partof thisapplication.

Fig. 20 is a side elevat ion ofa carrier, partly insection, illustrating how a cylinder may be rotatably mounted in'thecarrier.

Similar characters of reference are used to indicate the same partsthroughout the v eral' views.

The carrier herein'show'n includes a cylindrical' body 1, provided witha bottom 2 and a lid 3, the lid being hinged thereto by hinges l. Thebottom may be riveted to the body. The body may be provided withupholstering which can be held in place by a lining 4.; The carrier isto be mounted in the cab in the mostconvenient position withoutinterfering with the engineers position or duties. The upper edge of thecarrier is preferably mounted flush with the floor 5 of the engineerscab which is braced by the bar 6. The carrier is mounted on hangers 7and pins which are operated as hereinafter set forth. The carrier isheld against lateral displacement by hooks 9 which are attached to theframe 10. The hangers 7 are provided with braces 11 and the frame piece6 is provided with braces 12. The hooks 9 engage eyes 13 which arebolted to the carrier. An upholstered seat 14 is provided and mounted ona back 15 and platform 16. The seat is braced by the braces 17 and 18and held in operative position by rods 20 which project into Lbeam 21.Clutches 22 are attached to the back of the seat and engage the I-beam21, as shown in Fig. 3 to guide the seat down in the carrier and back topositions shown in Figs. 1 and 6. Means are provided for holding theseat in these positions. Rods 20 are mounted in brackets 23 which areattached to the platform 16 and rods 20 are slidably mounted in thebrackets 23. Spiral springs 24 are mounted on the rods and attachedthereto at their inner ends and rest against the brackets 23 for seats.A T-lever 25 is pivotally connected to the back 15 of the seat andprovided with handles 26. A T-bar 27 is pivotally connected to the lever25 and chains 28 are attached to the bar 27 and extended down underpulleys or idlers 29 and attached to the rods 20. lVhen the engineerwants to go down into the carrier, he pulls on the handles 26 andwithdraws the rods 20 from the I-beams 21. The seat and the platformwill instantly drop down in the carrier. Spring buffers 30 are attachedto the bottom of the platform to prevent severe bumps on the bottom ofthe carrier. When the seat drops, several things take place. A. springlock 32 is attached to the back of the seat and this look 32 will engagethe top channel bar 31 inside of the carrier, the carrier being providedwith channel bars for bracing purposes. Spring locks 33 will also engagethe platform 16 and hold the same down. The lid 3 Will close as soon asthe seat disappears in the carrier. The seat is held backat the top by alatch 34 which is attached to a frame piece and engages an eye orbracket 36 which is attached to the seat. When the seat drops, the eye36 slips off the latch 34. Springs 37 and 38 are attached to the framepiece 35 and bear against the lid 3 and a hinged latch 39 is connectedto the frame piece 35 and bears against the seat 15. The lid 3 bearsagainst the latch 39 and thus the seat and the lid are rigid with eachother until the seat drops. The latch 39 will swing upwardly and thesprings 37 and 38 will throw the lid down as soon as the seat passesbelow the latch 39. When the lid comes down, it will strike the verticalrod 40 which effects a release of the carrier. A disk 41 is mounted on ashaft 42. A bar 43 is pivotally connected to the disk 41 and has slot 44near the outer end. The vertical rod carries a wedge or spear 45 whichenters the slot 44 and will thus force the rod 43 outwardly and at therod 43 will turn the disk 41. The rods or pins 8 are pivotally connectedto the pitman rods 46 which are pivotally connected to the disk 41. Whenthe disk 41 is turned, the rods 8 will be drawn from the hangers 7 andthus release the carrier so that the carrier will drop out of theengineers cab. When the carrier starts down, pins 47 which are rigidwith the carrier will engage the pivoted bars 48 and these bars willforce the carrier to swing outwardly and thus throw the carrier farenough to fall outside of the railway track. In order to preventaccidental dropping of the rod 40 a lug 49 is provided on the rod 40 anda spring 50 is attached to the inside of the cylinder 1 and providedwith a lug 51 to support the lug 49 which is rigid with the rod 40.WVhen the seat drops down in the carrier, it will strike the spring 50and press the lug 51 from under the lug 49 and hold the same away untilthe seat is raised. Thus the lugs 49 and 51 will not interfere with theoperation of the seat. When the seat is raised, the rod 40 is broughtback to normal position. The lugs 51 and 49 will come to their normalpositions automatically. When the rod 40 is raised, it will adjust thepins 8 to their normal or supporting positions. When the rod 40 isforced down, the spear 45 draws the pins 8 inwardly. Provision is madefor locking the pins in the inward position. The bar 43 has a lug 52rigid therewith. The rod 40 has a spear or wedge 53 rigid therewithturned in the opposite direction to the direction of the wedge 45. Inthe downward motion of the rod 40, the lug 52 will be drawn against thewedge 53 and thus lock the bar 43 sta tionary. When the rod 40 is drawnupwardly, the wedge or spear 53 will engage the lug 52 and thus forcethe pins 8 outwardly. Means are provided for locking the lid 15 downclosed. Pivoted locks 54 are mounted in the lid by means of brackets 55.The lock is held in locking position by a spring 56 which is looselyconnected to the lever end of the look by a ring 57. The spring 56 isreinforced by a spring 59. A bolt 58 extends through the lid from theoutside and extends through the spiral spring 59 and through the spring56 and is provided with a nut 60. A. person within the carrier canrelease the lid by turning the nut 60 and forcing the spring 56 towardthe lid. The nut 60 is provided with a handle (31. The lid can also bereleased from the outside. A wrench can be applied to the bolt 58 on theoutside to turn the bolt to draw the lever end of the lock 54. in towardthe lid. This would release the lock. The carrier may be provided withany simple valve 62 for the use of a person within the carrier to let inair when needed. The lid 15 may be provided with aweight 63 for mak in acup 66 which is attached to the false.

bottom 67 by means of flanges 68. j The swinging discharging arms 48 areprevented from swinging out of place by the pins 47, the hangers 7, andby guards 69.

A variation of the carrier releasing devices is shown in Fig. 7. Insteadof the'bar 43, an arm 7 O is rigidly attached to the disk 41 and isloosely connected with a spring 71 which may be attached to'the interiorof the carrier 1. When the seat 14 F 5 drops down into the carrier, theplatform 16 will bear the spring 71 and the arm 70 down and thus turnthe disk 41 for operating the pitman rods 46.

A variation in thelid throwing means is J go gshown in Fig. 8. A weight72 may be used to throw the lid instead of the springs 87 and 38. I

Fig. 10 illustrates one way of making a double carrier. The seats andthe operating mechanism can be duplicates of the mechanism described.The carrier has two compartments instead of one. These compart ments mayhave communication with each other by an opening through the partition4073 which separates the compartments,the

opening being indicated in dotted outline.

A variation in the carrier releasing devices is shown in Fig. 11. Lugs74 are provided on the carrier 1. These lugs rest on .the armsll. Thearms 11 are braced by the bars 75 which are pivotally connected to thearmsll at their lower ends and hung on a bar 76 which is slidablymounted in double brackets 7 7 which are attached to the frame 10. Thebar 76 simply projects through the brackets 77 on one side and at theother side extends over the top of the brackets and is provided with alug 78 which projectsback through the brackets 77. This is done in forderthat a single movementof a single bar will release both armssimultaneously. The arms or bars 75 project between the brackets 77 andthe bar 76 and the lug 78 project through these bars as well as throughthe brackets 77. Means are provided for moving the bar 76. These devicesare shown in Figs. 11,13, and 18. A spear or wedge 79 ismounted on eachside of thecarrier and supported on the bars 76 and on bars 80 e5 'whichare attached to the cab frame. Small brackets 81 may be attached to theframe to prevent displacement of the wedges. The bars 76 have slots 82-through which the wedges 79 operate to move these bars when the lid 3strikes the wedges. The bars 80 have slots 83 into which the wedges 79pro ject so that the wedges will not yield in wrong direction. The bars76 must move but the bars must not move. Shoving the wedges 79 down willmove the bars 76 out 75 of the ends of thebars 7 5 and thus let thesebars swing down so that the carrier will drop downwardly. The bars 75will drop down and rest on thebrackets 84 and the guards'85 will preventthe bars 75 from falling forward in the cab. Fig. 19 illustrates how thelidmay be made to fit down on the upper edge of the carrier, making awaterand air tight joint.

A different releasing mechanism is shown 35 in Figs. 12, 14, 15, and 16from the releasing devices shown in figures previously described. A bar86 is mounted in brackets 87 which'are to be attached to the cab frame.The bar 86 isprovided with roller bearings 88 and a slidable bar 89 ismounted on the roller bearings 88, it being understood-that similar barsto bars 86 and 89 are mounted on each side of the carrier. The carrieris supported on the bars 89 by means. of lugs 95, 90 and ball bearings91 which are mounted in the lugs 90. The bars 86 and 89 stand lockedtogether by a key 92 which projects above the bar 89 and bends under andprojects up through the bars 86 and 89. The key 92 is held in place by aspring 93 which is attached to the bar 86. When the lid 3 falls it willknock the key 92 out-of the bar 89 and on further motion'of the lid, itwill strike a wedge 94 which will move. the bar 89 until the cut-out 95registers with the cutout 96 in the bar 86. The bearings 91. and thelugs 90 of the, carrier will drop through. these cut-outs andthusrelease the carrier so that the carrier will be discharged as abovedescribed. The lid 3 is provided with lugs 97 and 98 forstriking the key92 and the wedge 94 respectively. 11f such releasing devices as heredescribed are used, such releasing devices as are shown in previousfigures would be dispensed with. Thebottom of the carrier couldbeconstructed differently. The bottom:can be made concave, as shown inFig. .12. The spaces 99 betweenthe channelirons 31may be inclosed toform annular air spaces within the carrierto aid' in making thecarrier'float. These spaces may be inclosed by sheet metal 100.

The brakes of the train may be applied b the falling of the carrier. Thecarrier is provided with a lug 101 and the handle .102. of the anglecock of a trainline103 may be projected into the path of the lug 101.When the carrier drops downwardly the lug-101 will turn the vangle cockand thus set the brakes. At the same time, the main throttle may beclosed. A lug is made rigid with the carrier. A hooked rod 106 isoperatively connected with the throttle 107 and the hook thereonprojects under the lug 105. The rod 106 is connected to a chain 108which runs over an idler sprocket wheel 109 and this chain is connectedto a bar 110 which is provided with a lug 111. The bar 110 is suspendedfrom a bar 112 which is mounted rigidly in brackets 113 so that the bar110 is slidable. When the carrier drops downwardly, the lug 105 willpull on the bar 106 and thus draw the bar 110 so that the lug 111 willactuate the throttle 107 to close the same. When the carrier drops aboutnine inches, it will swing forward at the top so that the lug 105 willbe disengaged from the rod ,106. During this operation, a sanding of thetrack will also be effected. A chain 11A is connected to the bar or rod106 and runs over anidle sprocket wheel 115 and is connected to a bar116 which is connected to the handle 117 of the sanding device so thatthe sand will be discharged by the air on the tracks. 118 indicates asanding device of ordinary construction.

Simultaneously with the above described operations, a reverse lever 119may be actuated to reverse the engine. lug 120 is made rigid with thecarrier. A lever 121 is pivotally mounted in the cab with one endprojecting under the lug 120 and the other end positioned near thereverse lever 119. A bar 122 may serve as a guide for the lever 121.When the carrier drops downwardly, the lug 120 will actuate the lever121 and this lever will actuate the reverse lever 119.

A variation in the carrier is shown in Fig. 20. A cylinder 123 ismounted in the carrier 1 and is made rotatable therein so that if thecarrier turns over to any extent, the cylinder 1255 need not necessarilybe turned. Ball bearings 12 1 are provided to prevent friction againstthe carrier 1. The asbestos lining 125, shown in Fig. 0 may be used inall the variations shown.
